The velocity of the ball in ft/sec, when t = 1 second is equal to -12 ft/sec.

Given the following data:

To calculate the velocity of the ball in ft/sec, when t = 1 second:

Mathematically, the velocity of an object or physical body is equal to the differentiation of it's position function.

Velocity = s'(t)

Velocity = [tex]s(t) = -16t^2 + 20t + 100[/tex]

[tex]Velocity = -32t + 20[/tex]

Substituting the value of time (t), we have:

[tex]Velocity = -32(1) +20\\\\Velocity =-32+20[/tex]

Velocity = -12 ft/sec

Answer:

1/3.  To reduce a fraction, divide both the numerator and denominator by the GCF.

Step-by-step explanation:

short - S

long - L

L=10+S

L+S = 48

SINCE L=10+S

10+S+S=48

10+2S=48

2S=48-10

S=38/2=19

SHORT=19CM

LONG=10+S=10+19=39CM

Answer:

(1,6)

Step-by-step explanation:

f ^− 1 ( x )  =  x/2  − 4

That is the inverse

The value of the function, for x=-2 is 4.

The given function is f(x)=2x+8.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

When x=-2, we get

f(-2)=2(-2)+8

=4

When x=0, we get

f(0)=2(0)+8

= 8

When x=5, we get

f(5)=2(5)+8

= 18

Therefore, the value of the function, for x=-2 is 4.

Answer:

white

4 were sold

3 more gray were sold than white

3 colors sold 10 or more

Answer:

a) White

b) 3

c) 3

Step-by-step explanation:

a) White as it is the shortest bar (has the lowest height and only has 4 t-shirts sold)

b) According to the bar graph, 7 grey t-shirts were sold and 4 white t-shirts were sold. Subtracting 4 from 7 = 7-4 = 3

Hence, 3

c) At least 10 T-shirts sold, suggests that it was greater than or equal to 10. According to the graph, black has 12, tan has 11, and brown has 10. Hence,

3 colors had at least 10 t-shirts sold.

Answer:

y ≤ -1/3x+80/9

Step-by-step explanation:

(1). 0.75(x)+2.25(y) ≤ 20

0.75 - Number of arcade games (X).

2.25 - Number of snacks (Y).

20 - The total.

(2). 0.75x+2.25y≤20

(After multiplying the x's and y's together, with the numbers).  

(3). 0.75x (-0.75x) + 2.25y ≤ 20 (-0.75x)

(Subtract -0.75x to each side, which allows the equation to get closer to the answer).

(4). 2.25y       -0.75x + 20

   ————   =   ————

    2.25            2.25

(Divide by 2.25 to each side).

(5). y ≤ -1/3x + 80/9

The total number of ways a girl can choose a two-piece outfit from 9 blouses and 8 skirts is 72.

Permutation is a mathematical calculation of the number of ways a particular set can be arranged, where order of the arrangement matters.

[tex]^{n} P_{r} = \frac{P!}{(n-r)!}[/tex]

Where,

[tex]^{n}P_{r}[/tex] is permutation

n is the number of objects

r is the number of objects selected.

According to the given question.

Total number of blouses = 9

Total number of skirts = 8

So,

the number of ways of choosing one blouse from 8

=[tex]^{8} P_{1}[/tex]

= [tex]\frac{8!}{(8-1)!} \\[/tex]

= [tex]\frac{8!}{7!}[/tex]

= [tex]\frac{8\times 7!}{7!}[/tex]

= [tex]8[/tex]

And the number of ways of choosing one skirt from 9

[tex]^{9} P_{1} \\= \frac{9!}{(9-1)!} \\= \frac{9\times 8!}{8!} \\=9[/tex]

Therefore,

The total number of ways of choosing two piece outfit from 9 blouses and 8 skirts

= [tex]^{8} P_{1} \times ^{9} P_{1}[/tex]

= [tex]8 \times 9[/tex]

[tex]= 72[/tex]

Hence, the total number of ways a girl can choose a two-piece outfit from 9 blouses and 8 skirts is 72.

Step-by-step explanation:

Step 1: Divide both sides by 4.

Step 2: Check if solution is correct.

Therefore, x = 6.4.

Answer:

4x = 25.6

4x = 256 / 10

x = 256 / (10×4)

x = 64 / 10 (256 ÷ 4 = 64)

x = 6.4
